4 — Strategic scenarios ​

This step configures the stakeholders (SH) — potential attackers — then automatically generates the corresponding strategic scenarios (SH → target zone pair).

Stakeholders (SH) ​

Table of potential risk sources:

ColumnDescription
SelectedCheckbox — is the SH taken into account in the generation
SH typeSelection of a predefined type from a catalogue (code + label) — pre-fills the label, level, type and vulnerabilities typically associated
LabelName of the SH, editable
Lvl.Threat level (1 to 3)
CategoryExternal, Internal, Error
Access zonesCheckboxes — zones this SH has access to
✕Deletes the SH

The + Add a stakeholder button creates a new row with default values (opportunistic external attacker, level 1).

Scenario generation ​

The ✨ Generate strategic scenarios button is active as soon as at least one SH is selected. It combines the selected SHs with the access zones and checked vulnerabilities to produce the scenarios.

If no scenario is generated

Generation requires checked vulnerabilities on the access zones or on the SHs to identify an applicable intrusion rule (phase A). Two solutions:

  • Go to Topology, open each access zone and check vulnerabilities (V1, V2, V9…).
  • Select a predefined SH type in the table, which automatically associates typical vulnerabilities with the SH.

Generating operational scenarios ​

Once strategic scenarios are present, the ⚔️ Generate all operational scenarios → banner triggers the generation of detailed attack chains for all selected scenarios and automatically switches to step 5 — Operational scen.
